Abstract
Curiosity has four instruments that study the chemistry of Martian materials. Two of them focus on elemental abundances. ChemCam is a remote sensing instrument, able to detect the elemental composition of a rock or soil from a distance of up to 7 meters by shooting it with a laser, a technique deployed in space for the first time on Curiosity. The Alpha Particle X-Ray Spectrometer (APXS) is a contact science instrument to examine the compositions of rocks and soils reached by the arm, and has a long Martian heritage.Curiosity’s Chemistry Instruments
